as far as Mouse's packmates are concerned i would put good odds that somewhere in the BAT during some sort of Chicken Pizza level fight somebody is going to open a WAY and we will see a whole PACK of Temple Dogs come running.
(of course i would also put odds that there is a Mrs Mouse running about somewhere)
Two things come to mind, here. One, from the outset, I thought that Jim made it pretty clear that not all of the litter was retrieved and turned over to the monk. Not just Mouse, but that more than one of the puppies wasn't there. It just seemed to me that if the monk was indicating that only one littermate was absent, he would have said something closer to, "Where's the other one, did you see what happened to him?"
The question that would follow on from that, of course, is -- what would have happened to the puppy or puppies who didn't make it into the lifeboat, so to speak? Of course death is always a major possibility. Although a very sad outcome, it's what one might naturally expect evil demons to want to do to such powerfully good entities. But that doesn't fit, because if so, why pup-nap them out of Tibet in the first place? You'd think that the bad guys would kill the puppies as soon as they seized them, or if not, due to the danger of other Foo dogs charging to their defense, then as soon as they had put sufficient distance between themselves and the monastery.
So what exactly were they all seized
for?? Did whoever was calling the shots for the demons plan to do something or to trick the baby puppies in some way, to skew them from serving goodness to serving evil? Will Mouse face his own personal Civil War in the BAT, brother against brother, each equally loyal and dedicated to opposing sides? Mouse to Harry and the protection of humankind and of the world as we know it versus Brother-BadDog to some misguided belief that the bad guys ought to triumph?
Second point is, even with reincarnation and the Wheel of Karma, Mouse came into Harry's life while still a tiny puppy. So, no Mrs. Mouse yet at that point, not in this present lifetime. That doesn't mean that there won't be one coming along, of course. Mouse may be a bachelor knight-errant now, selflessly dedicated to personally guarding Maggie Jr. and Molly and Harry himself, but I certainly hope that one day there comes along a strong, lithe candidate who catches Mouse's eye. Sure, the timing of the meet-up will be maximally inconvenient, but that doesn't mean that the chemistry won't flow.
I guess I was wrong -maybe it's three things, not two. Third point, Ancient Mai said Foo dog, and she doesn't seem to be the kind of wizard who carelessly misspeaks. She didn't say Temple dog. I kinda suspect that Mouse
isn't a scion, a Temple dog, a mixture of celestial and mortal canine ancestries. I think he's all Foo.
Maybe he needs a T-shirt logo like the vest a service dog wears so they're immediately recognizable. "All Foo All The Time!," or something.
Harry's birth was planned for a purpose. And we know that Uriel, on behalf of TWG's intentions for the world, isn't at all above playing chess with earthly lives when he deems it necessary. So, was that litter whelped on purpose in order to have young strong Ice Demon adults in place for some upcoming Asian cataclysmic battle? Not Temple dogs, but in fact True Foo all the way?
